V EGG-BEATER.

Specification of Letters Patent.

Patented Nov. 4, 1913.

Application filed June 21, 1912. Serial No. 705,025.

i To all whom it may concern:

Be it known that I, THOMAS HOLT, a citizen of the United States, and a resident of Tarryto-wn, in the county of Westchester and State of New York, have invented a new and Improved Egg-Beater, of which the following is a full, clear, and exact description.

Among the principal objects of the present invention are: To provide means, manually operative, for rotating suitable flukes;

to eliminate friction in the operation of the apparatus; to reduce the space required for the storage and transportation of the apparatus; and to simplify the construction and economize in the cost of production of the same.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views, and in which Figure 1 is a side view of an apparatus constructed and arranged in accordance with the present invention, the handle of the same being shown in section; Fig. 2 is a detail view, on an enlarged scale, showing in section a fragment of the handle, the end of the rotary shaft, a guide piston, and spring for operating the piston; Fig. 3 is a detail view. showing the ferrule for the handle, and in section the driving shaft and oppositely-disposed spirals mounted thereon, the section being taken on the line 33 in Fig. 1; Fig. 4 is a cross section of the beater head, taken on the line 4-4 in Fig. 1; Fig. 5 is a vertical section, on an enlarged scale, on the line 5-5 in Fig. 1; and Fig. 6 is a detail view, showing the Whipper end fragment of the apparatus.

The present invention relates to that class of egg-beating apparatus, wherein the eggs are whipped by a rotary device immersed partly or entirely within the eggs when broken into a suitable dish or receptacle. In the present instance the whips are constructed from suitable wire disposed in three parallel extensions 10, 10. The exten-v sions 10, 10 are spaced apart, as seen best in Fig. 1 of drawings, and radially removed whips are constructed, the said strands be,

ing wrapped upon the shaft in spiral fashion, to form spiral threads 12, 12.

In forming the threads 1.2, 12 and the whips having the extensions 10, a single length of wire is used, which is bent at the middle to form a loop 13 to closely fit the surface of the shaft 11. Prior to bending the extensions 10 of the whips, the wire forming the threads 12 is planted upon the shaft 11 by having the loop 13 securely fastened to the .said shaft while the free ends are held and twisted to form the even spiral for the threads 12, seen in Fig. 1 of drawings. the turn of the wire is shortened, and at At the lower end of the shaft,

edly secured to the shaft 11.

The wire forming the spirals 12, being thus formed, requires no subsequent cleaning or care, suchas would arise if the shaft and wire were dipped or soldered after being planted on the shaft 11. As indicated, it is after the threads 12 have been thus formed that the wire is bent to form the parallel extensions 10, 10 of the whips. The extreme ends of the wires forming the whips are turned to close the passage between the outer and the intermediate extensions 10. The said ends are thus turned to prevent the removal of flukes 14, 14. The flukes 14, 14 are constructed from suitable metal, having tabs 15, 15 extended perpendicularly from the body of the flukes 14, 14, said tabs having perforations 16, through which is threaded the outer extension 10 of the said whips. The perforations 16 are enlarged, so that the movement of the flukes 14 is unrestrained.

The shaft 11 is loosely secured at the lower end to a foot-rest, which, as seen in the drawings, is preferably formed as an inverted cup member. The rest'17 is held between a collar 18, fixedly secured to the shaft 11, and a loose ferrule 19 mounted on the said shaft between the foot-rest and the lower end of the windings of the wire forming the threads 12. The freedom of movement allowed the ferrule 19 permits the foot-rest to rock about the shaft 11, to form for the said shaft a universal joint, which permits the foot-rest 17 to solidly adjust itself within the receptacle containing the material being operated upon. The joint thus formed between the rest 17 and the shaft 11 is simple, economical and efficient.

The upper end of the shaft 11, where the same extends beyond the loop 13, is seated in a bore centrally provided in a guide block or piston 20. The piston 20 and a spring 21 for operating the same are both held within the central bore formed in a sheath handle 23. The bore of the handle 23 is closed by a ferrule 24 and a guide plate 25 held in the said ferrule.

The guide plate 25 is provided with a perforation 2G, shaped to conform loosely to the looped wire extensions forming the threads 12, 12 on the shaft 11. The plate 25 is rigidly held in the ferrule 24, the

rigidity being secured by the common ex pedient of forcing the plate 25 within the ferrule 24. o

The outer edge 27 of the ferrule is overturned upon the plate 25 in the manner:

. 28 of the ferrule is crimped to sink the same into the body of the handle 23, to thereby secure the ferrule rigidly upon the said handle.

The spiral spring 21 enfolds a contracted portion of the piston 20. The said spring is formed to a length and tension suflicient to normally extend the piston 20 and shaft 11 mounted therein until the loop 13 rests against the plate 25, as seen in Figs. 1 and 2. The convolutions of this spring are sufliciently wide to permit the extension of the shaft 11 and the piston 20 within the handle, as shown by dotted lines in Fig. 1 of drawings. It is during the extension of the shaft 11 and piston 20 within the handle 23 that the said shaft is rotated, and the whips connected therewith are gyrated.

It is to reduce the friction of rotation of the shaft 11, and to increase the wear between the same and the piston 20 that I have provided a bearing ball 29 to take the end thrust of the said shaft.

When constructed and arranged as shown and described, the operation of the apparatus is as follows: The operator, having deposited the eggs, freed from their shells, in a suitable dish or receptacle, places the whips in the dish, resting the apparatus upon the foot-rest 17. In disposing the apparatus, the same is manipulated by the handle 23. The handle 23 is now depressed, the spring 20 contracting to permit this action. The handle 23 and the plate 25 being held nonrotatable, the threads 12, 12, passing through the perforations 26, impart to the shaft 11 a rotation rapid in proportion as the movement of the handle is fast or the pit-ch of the threads 12 is short. Then the pressure on the handle 23 is relieved, the spring 21 operates to lift the handle, or to maintain the pressure of the rest 17 on the bottom of the receptacle while the handle is being lifted by the operator. In this manner, the whips of the apparatus are maintained constantly in the material being operated upon. During the lift of the handle 23, a rotation is imparted to the shaft 11, the reverse of that imparted during the depression of the said handle. The rotation of the shaft 11 gyrates the whips formed by the wire extensions 10, 10 and the flukes 14 carried thereby. The width of the body of the flukes 14 is sufiicient to form in the wake thereof, during the g'yration of the whips, a gap in the material, into which the air rushes to froth the material. Due to the drag of the flukes through the material,

- they rotate about the extension 10 upon which they are mounted, to follow after the said extension 10. Being loosely mounted on the vertical extension of the whips, the fiukes quickly accommodate themselves to the rapid reversal of the direction of gyration of the said whips during the operation of the apparatus.

It will be understood that, while I have herein shown the whips provided with the fiukes 14, the fiukes may be dispensed with, the extensions 10 of the whips operating to froth the material effectively, though not so rapidly as when aided by the more violent action of the flukes.

As best seen in Fig. 6 of drawings, the whips and fiukes, if mounted thereon, are set at an inclination backward from the line of gyration. By so inclining" the whips, the material being operated upon is lifted or thrown upward from the bottom of the receptacle, to aid in the aeration necessary to the beating or successfully whipping of the material.

It will be understood that the present described apparatus admits of the operator changing the angle of inclination to suit his or her desire or convenience.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1.
